These materials will provide following advantage as Skin sheet on light airplanes of recent design and construction generally is alclad 2024-T3. Each wing on an aircraft has two wing skins, one lower and one upper, that provide the largest aerodynamic surface on the plane. Recently developed alloys, such as 5086, 5454, 5456, 6070, and the new weldable aluminum-magnesium-zinc alloys, offer strength advantages over those previously mentioned. As a wing bends upwards the main compressive loads act on the top skin along the length of the wing and therefore a large number of stringers are visible across the width. Difficulties in quality control have resulted in low utilization of electric resistance welding for primary structure. Titanium grade Ti-6/4– Composition Aluminum skin is normally of the minimum practical thickness: 0.015 to 0.025 in. In part 5 we looked at the role that the airfoil profile plays in determining the flying characteristics associated with its selection. & micro-structure.
